DMX512 CONNECTION

At last unit, the DMX cable has to be terminated with a terminator. Solder a 120Ω 1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a 5-pin XLR plug and plug it in the DMX output of the last unit.
Connect the unit together in a daisy chain by XLR plug from the output of the unit to the input of the next unit. The cable cannot branched or split to a Y cable. DMX 512 is a very high-speed signal. Inadequate
or damaged cables, soldered joints or corroded connectors can easily distort the signal and shut down the system.
The DMX output and input connectors are pass-through to maintain the DMX circuit when one of the units’ power is disconnected.
Each lighting unit needs to have an address set to receive the data sent by the controller. The address number is between 0-511 (usually 0 & 1 are equal to 1).
The end of the DMX 512 system should be terminated to reduce signal errors.
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+), Pin 4/Pin 5: Not used.

APPENDIX A

CARE AND MAINTENANCE

TROUBLESHOOTING

Following are a few common problems that may occur during operation.

The unit does not work – the light and fan do not turn on

Check the connection of power and main fuse.
Measure the mains voltage on the main connector.

Not responding to DMX controller

DMX LED should be on. If not, check DMX connectors, and cables to see if they link properly.
If the DMX LED is on and no response to the channel, check the address settings and DMX polarity.
If you have intermittent DMX signal problems, check the pins on the connectors or on the PCB of the unit or the previous one.
Try to use another DMX controller.
Check if the DMX cables run near or run alongside to high-voltage cables that may cause damage or interference to the DMX interface circuit.

CLEANING

The cleaning of internal must be carried out periodically to optimize light output. Cleaning frequency depends on the environment in which the ﬁxture operates damp, smoky or particularly dirty surroundings can cause a greater accumulation of dirt on the ﬁxture’s optics.

Clean with soft cloth using normal glass cleaning fluid.
Always dry the parts carefully.
Clean the external optics at least every 30 days.

Fan Speed and Control

All Vari-lite and Strand lighting luminaires will be governed by the same Fan speed v Noise levels v Maximum power output rules as detailed below. These noises related to these levels will confirm to Noise Criteria levels details of which are contained within the document. There are 3 control parameters that can be selected separately or in conjunction when permitted to manage Fan speed v Noise levels and Maximum power output.

NOTE: Not all fixtures have all modes or functions refer to the DMX map and User interface menu tree to see if your product has one or more of these functions Item 1 – Fan ‘v’ Output Preset Modes These modes are selectable at either/or the fixtures DMX control channel or via the fixture user interface screen. The section of the modes works in conjunction with Item 3 and will also activate or deactivate Item 2. Boost mode – LED output boosted to >120% of standard output fan speeds increased manage heat level of LED (may be limited to only run for XXhrs). The fixture will not exceed NC45 – NC55 sound levels in this mode Standard mode – Full LED Output + Fan Spin at top speed (loudest setting). The fixture will not exceed NC40 sound levels in this mode Studio Mode – Fan speed reduced to the appropriate amount to reduce dB levels

10% of full speed + LED @ max output approximately 80% of Standard output at an appropriate level to ensure LED work at optimum temperature and output efficiency (fan speed remains at a constant speed and do not ramp up or down) NC35 Whisper mode – Fan speed reduced to the appropriate amount to reduce dB levels to >30% of the full speed + LED Max output approximately 60% of Standard output at the appropriate level to ensure LED work at optimum temperature and output efficiency (Fan speed remains at a constant speed and do not ramp up or down) NC25 Silent Mode – ideally Fans do not spin + output capped at the appropriate level to ensure LED work at optimum temperature and output efficiency (Fan should never switch on in this mode or change speed if they on) NC15 target level.

HOW TO OBTAIN WARRANTY SERVICE

A copy of the Strand Limited Warranty was included in the shipping package for this Strand product. To obtain warranty service, please contact customer service at 1-214-647-7880, or

entertainment.service@signify.com and request a Return Material Authorization (RMA) for warranty service. You will need to provide the model and serial number of the item being returned, a description of the problem or failure, and the name of the registered user or organization. If available, you should have your sales invoice to establish the date of sale as the beginning of the warranty period. Once you obtain the RMA, pack the unit in a secure shipping container or in its original packing box. Be sure to clearly indicate the RMA number on all packing lists, correspondence, and shipping labels. If available, please include a copy of your invoice (as proof of purchase) in the shipping container. With the RMA number written legibly on or near the shipping address label, return the unit, freight prepaid, to

As stated in the warranty, it is required that the shipment be insured and FOB our service center.
IMPORTANT! When returning products to Strand for repairs (warranty or out-of-warranty) from a country other than the USA, “Strand Lighting LLC”, must appear in the address block as the Importer of Record (IOR) on all shipping documentation, Commercial Invoices, etc. This must be done in order to clear customs in a timely manner and prevent returns.
